Making the gas ventilate which it should store in generation quantitative grasp manner

摘要

PROBLEM TO BE SOLVED: To easily estimate the production amount of a hydrate at a low cost by using a versatile apparatus.;SOLUTION: Natural gas G to be stored is passed through a medium W (water) stored in a formation reactor 9 to increase the inner pressure of the reactor 9 and the reactor is cooled to form a hydrate H of the natural gas G and the medium W. The amount of hydrate produced by the above process is estimated by detecting the pressures in the reactor 9 at plural points distributed in vertical direction using a general-purpose pressure gauge 24 and comparing the variation of the pressure distribution by a processor 25 with a relational data between the production amount and the pressure distribution obtained beforehand by a preliminary experiment.;COPYRIGHT: (C)2001,JPO
